More links

For 2A, 3A, and 6B:

Here are some links to the carbon and nitrogen cycles. I will be going over these in class so it would be good to study them at home.

Here's a link to the different relationships that inhabit a reef colony.

I will be displaying this during the next full class we have.

Another pyramid idea

1) Get a styrofoam cone.

2) Mark off the different trophic levels on the cone and label them accurately and accordingly.

Follow the rest of the steps that are in the previous post.

How to make the energy pyramid (just one idea I had)

Periods, 2A, 3A, and 6B:

In conferencing with many of you, I have seen that you are already researching the information to create your pyramid, but are confused as to how to make it 3D. I am going to give you a couple of ideas on how you can own this particular piece.

1)Get about 4 or more styrofoam shapes (disks, blocks, or spheres)of decreasing (small to large) size.

2) Stack the shapes with the largest on the bottom and with each size getting smaller as you reach the top.

3) Label each different shape accordingly (i.e. which trophic level it is?).

4) You can use actual models or pictures for your organisms. Make sure they are at the appropraite trophic level.

5) Remember to have a printed explanation of how the sun's energy flows through the trophic levels of your chosen ecosystem.

6) Be creative! Decorate your pyramid to reflect the ecosystem you have chosen.
